Andrology. 2023 May;11(4):710-723. doi: 10.1111/andr.13361. Epub 2023 Jan 9. ABSTRACT BACKGROUND: Germ granules are large cytoplasmic ribonucleoprotein complexes that emerge in the germline to participate in RNA regulation. The two most prominent germ granules are the intermitochondrial cement (IMC) in meiotic spermatocytes and the chromatoid body (CB) in haploid round…

Sci Rep. 2022 Dec 2;12(1):20818. doi: 10.1038/s41598-022-25336-6. ABSTRACT While sunlight may influence cognitive function through several pathways, associations of residential sunlight exposure with cognitive function are not well known. We evaluated associations of long-term residential sunlight exposure with cognitive function among a representative cohort of 1838 Finnish adults residing in…

Best Pract Res Clin Obstet Gynaecol. 2023 Feb;86:102298. doi: 10.1016/j.bpobgyn.2022.102298. Epub 2022 Dec 17. ABSTRACT Semen quality has declined especially among Western men. Experimental and epidemiological studies have shown potential links between exposure to environmental toxicants and poor male fertility. Some environmental exposures in utero can disrupt fetal testicular function…

Eur J Neurosci. 2023 Jan;57(2):242-257. doi: 10.1111/ejn.15882. Epub 2022 Dec 17. ABSTRACT Prenatal stress exposure (PSE) has been observed to exert a programming effect on the developing infant brain, possibly with long-lasting consequences on temperament, cognitive functions and the risk for developing psychiatric disorders. Several prior studies have revealed that…

Sci Rep. 2023 Jan 5;13(1):216. doi: 10.1038/s41598-022-27317-1. ABSTRACT Increased exposure to greener environments has been suggested to lead to health benefits in children, but the associated mechanisms in early life, particularly via biological mediators such as altered maternal milk composition, remain largely unexplored. We investigated the associations between properties of…

Eur J Oral Sci. 2023 Feb;131(1):e12912. doi: 10.1111/eos.12912. Epub 2023 Jan 4. ABSTRACT We evaluated associations between changes in dental anxiety and tobacco use, adjusted for general anxiety and depressive symptoms. The FinnBrain Birth Cohort Study data, collected at gestational weeks 14 and 34 and at 3 months postpartum, were…

Scand J Med Sci Sports. 2023 May;33(5):682-692. doi: 10.1111/sms.14293. Epub 2023 Jan 4. ABSTRACT This study examined longitudinal associations between parenthood-related factors and physical activity from young adulthood to midlife over a 19-year follow-up period. Participants (n = 761) at the ongoing Cardiovascular Risk in Young Finns Study responded to…

Genome Biol. 2022 Dec 27;23(1):268. doi: 10.1186/s13059-022-02837-1. ABSTRACT BACKGROUND: Genetic variants within nearly 1000 loci are known to contribute to modulation of blood lipid levels. However, the biological pathways underlying these associations are frequently unknown, limiting understanding of these findings and hindering downstream translational efforts such as drug target discovery.

Front Endocrinol (Lausanne). 2022 Dec 9;13:1071761. doi: 10.3389/fendo.2022.1071761. eCollection 2022. ABSTRACT INTRODUCTION: Environmental exposure during fetal life may disrupt testicular development. In humans, a limited number of studies have investigated whether these adverse effects persist into adulthood. Using data from a prospective, population-based birth cohort study, The Copenhagen Mother-Child cohort,…

Int J Mol Sci. 2022 Dec 11;23(24):15726. doi: 10.3390/ijms232415726. ABSTRACT Only 3-5% of heavy alcohol users develop acute alcohol pancreatitis (AAP). This suggests that additional triggers are required to initiate the inflammatory process. Genetic susceptibility contributes to the development of AAP, and SPINK1 mutation is a documented risk factor. We…
